Agents with ChatGPT

ChatGPT thinks. Codex works. ChatGPT 负责思考，Codex 负责干活。

The problem · 解决什么问题

中文 — ChatGPT 付费订阅的网页版额度大量闲置，Codex 却在消耗紧张的 API 额度做规划和 Review。本项目把"思考"交给你已付费的网页版 ChatGPT， Codex 继续负责本地执行。不用 API Key、不搞逆向代理——官方网页 + OAuth MCP 桥接，并提供明确授权的本地任务提交路径。

EN — ChatGPT Plus/Pro web quota sits idle while your coding agent burns scarce API/Codex tokens on planning and review. This project moves the thinking to the subscription you already pay for; Codex remains the local executor. No API keys, no reverse proxy — official web UI plus an OAuth MCP bridge with read/review tools and an explicitly authorized local task path.

What it is · 这是什么

中文 — 把 ChatGPT 网页版变成 Codex 编码会话的"规划与审查大脑"，执行权 仍由 Codex 的本地执行器掌握。你的仓库永远不会被上传：ChatGPT 通过 OAuth MCP 连接按需读取代码，并可通过本地 Codex App Server 提交任务。当前 CLI 按已选择的 full-access 模式运行执行器：Codex 可以使用 bridge 进程拥有的文件系统和进程权限； 网络默认关闭，只有任务明确设置 network: true 且本地 full-access 部署允许时才开启。 公开 MCP 接口仍保持固定的 14 个工具，其中外部写入仅限单独授权的审计镜像工具， 不新增通用 Shell 工具。

EN — Use the ChatGPT web app as the planning and review brain for your Codex coding sessions, while Codex keeps ownership of local execution. Your repository is never uploaded: ChatGPT reads exactly the lines it needs through an OAuth-protected MCP connection and may submit work through the local Codex App Server. The CLI deployment runs that executor with the user-selected full-access mode; network remains disabled by default and is enabled only for a task that explicitly sets network: true in this locally authorized deployment. The public surface remains a fixed 14-tool MCP contract with one separately scoped, exact-target audit-mirror writer.

Agent-prompt install · Agent 部署提示词

Prefer letting your coding agent do it? Copy the deploy prompt, the read-only smoke-test prompt, and the two-session multi-agent example from docs/agent-prompts.md. The classic one-paste install prompt below is unchanged and battle-tested:

中文 — 不懂 git、Node、终端？完全不需要懂。把下面这段话原样复制给你的 编码 Agent（Codex），然后去倒杯咖啡：

请帮我完整安装并配置 Codex with ChatGPT，全程自动，我是不懂技术的小白，
所有事情你自己做：

1. 环境自检：需要 git 和 Node.js ≥ 20，缺什么就自动安装
  （macOS 用 Homebrew，Windows 用 winget），同时安装 cloudflared。
2. 下载：把 https://github.com/G0K0U/agents-with-chatgpt 克隆到
   ~/codex-with-chatgpt（已存在就 git pull 更新）。
3. 构建：在该目录里执行 corepack pnpm install 和 corepack pnpm build。
4. 安装 Skill：把仓库里的 skill/SKILL.md 复制到
   ~/.codex/skills/codex-with-chatgpt/SKILL.md，并把文件中
   "The codex-with-chatgpt checkout lives at:" 那一行的路径改成实际克隆路径。
5. 首次配置：按 SKILL.md 里的 first-time setup 流程执行
  （运行 c2c setup，用内置浏览器打开 ChatGPT 配置连接器并输入配对码）。
   全程只用内置浏览器，禁止打开任何第三方浏览器。
6. 只有遇到需要我登录（ChatGPT / Cloudflare）、验证码或两步验证时才叫我，
   而且一次只告诉我一个动作。
7. 完成后给我看 ✓ 清单，并确认文件读取测试通过。我不懂 MCP、OAuth、
   Tunnel、端口这些词，不要向我解释；出了问题先自己修。

EN — Don't know git, Node, or terminals? You don't need to. Copy the paragraph below, paste it to your coding agent (Codex), and go grab a coffee:

Please install and configure "Codex with ChatGPT" for me, fully automatically.
I am a non-technical user — do everything yourself:

1. Check the environment: git and Node.js >= 20 must be available. Install
   anything missing yourself (macOS: Homebrew, Windows: winget). Also install
   cloudflared.
2. Download: clone https://github.com/G0K0U/agents-with-chatgpt into
   ~/codex-with-chatgpt (if it already exists, git pull to update).
3. Build: inside that folder run `corepack pnpm install` then `corepack pnpm build`.
4. Install the Skill: copy skill/SKILL.md to
   ~/.codex/skills/codex-with-chatgpt/SKILL.md, and update the line
   "The codex-with-chatgpt checkout lives at:" to the actual clone path.
5. First-time setup: follow the SKILL.md "first-time setup" workflow
   (run c2c setup, configure the ChatGPT connector in the BUILT-IN browser,
   enter the pairing code). Never open a third-party browser.
6. Only interrupt me for logins (ChatGPT / Cloudflare), CAPTCHAs or 2FA —
   and give me exactly ONE action at a time.
7. When done, show me the ✓ checklist and confirm the file-read test passed.
   I don't know what MCP, OAuth, tunnels or ports are. Don't explain them.
   If anything breaks, fix it yourself first.

Updates · 更新 — The Skill checks GitHub once a day and updates itself when a new version is released; no action needed. You can also say "更新 Codex with ChatGPT" anytime. / Skill 每天自动检查一次 GitHub，有新版本会自动更新，无需任何操作； 也可以随时对 Codex 说"更新 Codex with ChatGPT"。

The sections below are in English. 以下详细内容为英文，中文完整版见 README.zh-CN.md。

Install → Setup → Use (manual)

1. Install the Codex Skill: copy skill/ to ~/.codex/skills/codex-with-chatgpt/.

2. Tell Codex: "Set up Codex with ChatGPT." (中文: "使用 Codex with ChatGPT 完成首次配置。")

3. Use Codex normally: "Use Codex with ChatGPT to implement XXX."

That's the whole manual. You don't need to know what MCP, OAuth, tunnels, ports or localhost are — Codex configures everything automatically and you just see:

Codex with ChatGPT

✓ Project detected
✓ Workspace Bridge started
✓ Secure connection established
✓ ChatGPT connected
✓ File read test passed

Ready.

The only steps that may need you: logging into ChatGPT (and, if you want a stable hostname, logging into Cloudflare once). A new workspace also asks you to create a ChatGPT Project (collection) once — pick project-only memory, name it after the workspace. If the sidebar has no Projects row, hover Chats, open the … menu, and choose Organize by project. Codex then saves that collection link and starts chats from that page. Existing workspaces that already have a C2C chat stay on the old one-conversation style until you ask to switch.

Optional stable hostname

The default public address is a temporary Cloudflare URL. It changes when the bridge restarts, and Codex repairs ChatGPT by deleting that workspace's connector and adding it again.

If you have a Cloudflare account and a domain already on Cloudflare, first-time setup (and the next coding session, once) will ask whether you want a stable hostname such as c2c-<project>.your-domain.com. That path opens a browser so you can authorize Cloudflare. After that, the ChatGPT connector keeps working across restarts. If you skip it, or login fails, Codex stays on the temporary address — same features, just a slower repair.

Credentials stay in the OS app state directory, not in the project.

• Control plane (Computer Use): Codex and ChatGPT exchange tiny structured [C2C] state messages — INIT → PLAN → EXECUTED → REVIEW → DONE. No diffs, no logs, no file bodies are ever pasted.

• Data plane (MCP): ChatGPT pulls what it needs through the 9 existing read/review tools and can use the separate submit_codex_task, get_codex_task, cancel_codex_task, and execution_queue tools when explicitly authorized. The separately scoped write_engineering_ai_audit_mirror tool writes only the operator-configured Engineering AI status target (disabled unless C2C_ENGINEERING_AI_WORKSPACE_ID is set).

• Independent review: after Codex executes, ChatGPT inspects the actual git diff and test records through MCP — it never trusts "all tests passed" claims blindly.

Permission model (short version)

• Full local executor: the CLI starts the official Codex App Server with full filesystem and process access, matching the selected Codex/ChatGPT local execution mode. Network is off by default; a submitted task can edit any host path available to the bridge process, and only an explicit network: true request can opt into the locally authorized network capability.

• Fixed public contract: ChatGPT still reaches execution through the three task lifecycle tools and the separately scoped queue-control tool; it cannot call an arbitrary MCP shell or App Server method directly. The only external write is the separately scoped exact-target audit mirror; the bridge retains OAuth scope, workspace identity, owner, and session checks.

• Multiple authorized workspaces: one connector can select only registry entries bootstrapped by the local bridge; every entry has a stable id and a canonical root. Public read/review tools remain workspace-relative.

• Output protection remains: OAuth tokens, pairing codes, credentials, and host paths are still redacted from logs, task metadata, session checkpoints, and released command output where those filters apply. Full executor access does not make raw credentials part of the MCP response contract.

• Knowing the URL grants nothing: the public MCP endpoint requires OAuth 2.1 (PKCE S256, dynamic client registration, rotating refresh tokens). Without a token: 401. Wrong workspace: 403.

• The model never sees long-lived credentials: the only secret that ever touches a browser is a one-time pairing code (5-minute TTL, 5 attempts, rate-limited, destroyed on use).

Public infrastructure boundary

This repository includes source code, architecture, and generic tunnel integration only. It does NOT ship the maintainer's website/domain/tunnel, Cloudflare account, tunnel ID, certificates, OAuth state, runtime state, endpoints, or credentials. Each user configures their own tunnel/hostname or uses local/no-tunnel mode (--no-tunnel).

Status & disclaimer

Bootstrap upgrade verified end-to-end: one authorized connector can select the registered engineering workspace and the bridge workspace, persist sessions, resume task metadata after restart, and run the CLI executor in full-access mode. The full-access choice is intentional: anyone holding the connector's execution scopes can direct local Codex actions within the OS permissions of the bridge.
